Patient satisfaction with out-of-hours services;

how do GP co-operatives compare with

deputizing and practice-based arrangements?

Cathy Shipman, Fiona Payne, Richard Hooper and Jeremy Dale

Abstract

Background Although the rapid growth in general practi-tioner (GP) co-operatives has met with GP satisfaction, little is known about patient satisfaction. This study compares patient satisfaction with co-operative, GP practice-based and deputizing arrangements within one geographical area 15 months after a co-operative had become established; and with telephone, primary care centre and home consultations within the co-operative.

Methods A validated postal questionnaire survey of weighted samples of patients making contact with the co-operative, practice-based and deputizing arrangements was undertaken.

Results A total of 1823 (53.2 per cent) patients responded. There were no significant differences between organizations in terms of overall satisfaction, but patients using practice-based arrangements were significantly more satisfied with the waiting time for telephone consultations (p < 0.001) and more satisfied with waiting times for home visits than deputizing patients (p = 0.020). Within the co-operative, overall satisfaction, satisfaction with the doctor’s manner and with the process of making contact was greater among those attending the primary care centre, and satisfaction with explanation and advice received greater than for patients receiving telephone consultations alone (p < 0.01). Those receiving telephone advice reported increased information needs and help seeking during the following week (p < 0.05).

Conclusions Overall, patients were as satisfied with the co-operative as with practice-based or deputizing service arrangements, although many concerns were expressed about the quality of service provision. Differences in satisfaction were greater between forms of service delivery within the co-operative. Dissatisfaction with telephone consultations needs to be considered, together with issues relating to equity in access to out-of-hours’ primary care centre consultations and the potential impact of NHS Direct.

Introduction

New forms of out-of-hours general practitioner (GP) arrange-ments have encouraged a shift of care from within the home to

primary care centre or telephone consultations.1–3 Although

some evidence suggests that these changes have led to improved

quality of life for GPs,4the impact that this has had on patients

remains unclear.

Salisbury found few differences between patient

satisfac-tion with co-operative or deputizing services.5,6Higher levels

of dissatisfaction than previously reported were in part attribu-ted to changing patient expectations, lack of valid comparative questionnaires in previous studies, and the age structure and ethnicity of the study population. Satisfaction was highest amongst patients visited at home and lowest for those receiving telephone advice. However, the findings were compromised because most patients using the deputizing company were resident outside the district served by the co-operative and the study occurred in 1995 before organizations could adapt to new national terms and conditions for out-of-hours services. In

a study of smaller GP co-operatives, Hallam and Henthorne7

found little difference in patient satisfaction between home visits or primary care centre consultations, although less satis-faction was reported with telephone consultations.

Patients have indicated greater satisfaction with

practice-based rather than deputizing services,8 but direct comparison

between practice-based and co-operative arrangements has been lacking.

The present study aimed to compare patient satisfaction with a GP co-operative, a deputizing service and GP practice-based arrangements in one geographical area and to compare satisfaction with the different forms of service delivery pro-vided by the co-operative. We replicated the methods used by

Salisbury, to allow comparison.5

The study was conducted in an inner London Health Authority with a socially deprived population of approximately 730 000. The co-operative had been established for 15 months and had a membership of 290 GPs. In addition, 110 GPs used practice-based arrangements (rota or own on call) at varying times, but also directed calls to a deputizing doctor service. Patient calls to practice-based arrangements were almost all received by the deputizing service, which provided an answering service. Only about 5 per cent of GPs used neither

the co-operative nor the deputizing answering service.4

Method

We used a validated questionnaire developed by McKinley

et al.,9 and subsequently refined by Salisbury.5 It comprises an overall measure of satisfaction with questions grouped into sub-components shown in Tables 2 and 3 (below).

Questions were scored on a five-point Likert scale, with one indicating very dissatisfied and five very satisfied. Socio-economic data (age, sex and postcode) were gained both from information received by the co-operative and deputizing service and from the questionnaires.

Sampling

Patients were sampled from contacts with the GP co-operative and deputizing company between 21 April and 25 May 1997 (Table 1).

Certain patients were excluded to avoid potential distress to the very ill (Appendix 1); we also excluded those who made a second contact during the study period, patients whose contact was through a third party (except for children), and temporary residents.

Sampling was stratified according to organization and, within the co-operative, the form of service delivery. Under each of the five headings in Table 1 a different sampling proportion was used, to achieve roughly equal sample sizes based on predicted contact rates, subject to an anticipated non-response rate of 50 per cent. For a comparison of any two

categories, 250 patients in each would give 80 per cent power at the 5 per cent significance level to detect a difference of quarter of a scale point, assuming a standard deviation of one

scale point (as found by Salisbury).5

Process

Names and contact information were obtained from the co-operative and deputizing service, and code numbers were allocated to each sampled contact. Each sampled patient received a questionnaire 1 week after their out-of-hours con-sultation, and two reminders were sent at weekly intervals.

Analysis

Satisfaction sub-scales were calculated from questionnaire responses using Salisbury’s scoring system (personal commu-nication). Whereas the individual rating scores comprised Likert satisfaction scores, aggregation into sub-components of satisfaction allowed parametric analysis. Multiple regression analyses were undertaken on the overall satisfaction sub-scale to investigate differences between organizations and, for data from the co-operative, between types of consultation after allowing for the effects of potentially confounding socio-demographic variables. When comparing organizations, data on contacts with the co-operative were weighted to adjust for the stratification by form of service delivery. (Each form of service delivery at the co-operative was given a weight pro-portional to the total number of contacts of that form, divided by the number of such contacts actually sampled, with the average weight across all contacts for which data was available fixed at 1.0.) Post hoc comparisons of sample means were

undertaken using Tukey’s HSD test.10

Results

The samples

In all, 1288 (54.4 per cent) patients responded from the co-operative, 302 (47.8 per cent) from the deputizing service

and 233 (54.1 per cent) from GPs providing practice-based arrangements (Table 1).

More patients aged over 65 (66.5 per cent, 181/272) responded than younger patients (52.6 per cent, 1628/3094)

(x2¼18.49, df = 1, p < 0.001), and more men (57.4 per cent,

763/1329) responded than women (53.1 per cent, 1050/1976)

(x2= 5.69, df = 1, p = 0.017).

A greater percentage of recorded deputizing contacts (41.0 per cent, 117/285) had been made during night-time hours (22.00–07.59 h) than for practice-based (13.9 per cent, 26/187) or co-operative (27.4 per cent, 345/1261) organizations

(x2= 43.053, df = 2, p < 0.001).

Patient satisfaction

Overall levels of satisfaction did not differ by organization, nor did satisfaction with explanation or advice, doctor’s manner or the receptionist who took the initial call details (Table 2). There were significant differences between the organizations with the wait for a home visit (F = 3.96; df = 2.589; p = 0.020) and satisfaction with practice-based arrangements was signi-ficantly greater than with the deputizing service (post hoc comparisons using Tukey’s HSD tests). Significant differences were found with the wait for a telephone consultation (F = 11.7,

df = 2.688; p < 0.001) when satisfaction with practice-based arrangements was significantly greater than with either the co-operative or deputizing service (post hoc comparisons using Tukey’s HSD tests).

Patients using the co-operative were more satisfied with attendance at the primary care centre (base) than with telephone consultations for all satisfaction sub-scales ( p < 0.01). Satisfaction with attendance at the primary care centre was also significantly greater than with receiving a home visit for overall satisfaction, doctor’s manner and the process of contacting the service ( p < 0.01) (see Table 3).

Multiple regression analysis showed that differences between organizations remained non-significant after adjust-ing for variables that were strongly predictive of satisfaction (Table 4) (parsimonious regression model for overall satisfac-tion resulting from backward eliminasatisfac-tion of variables, selecting from: age and sex, whether patient was child or subject, wanting a home visit, telephone or primary care centre consultation, wanting a prescription; access to public transport, well enough to travel, recovery following consultation, receiving medica-tion or prescripmedica-tion, or referred to hospital). For co-operative patients, differences between the three forms of service delivery remained significant (Table 4).

levels of satisfaction (18.5 per cent compared with 8.5 per cent;

x2= 33.2, df = 1, p < 0.001).

Fewer primary care centre attenders reported attendance at A&E department or referral to hospital during the following week than all other patients (Table 5). More primary care centre attenders said that they had improved or recovered, and fewer reported consulting with a doctor at their surgery during the week following their out-of-hours contact. However, more also said that they felt well enough to travel at the time of contact (66.4 per cent) than those receiving home (11.5 per cent) or

telephone (44.8 per cent) consultations (x2= 228.74, df = 2,

p < 0.001), suggesting that they constituted a less ill sample

of patients.

Discussion

This study found overall patient satisfaction comparable for GP co-operative, practice-based or deputizing arrangements. However, patients using practice-based arrangements were more satisfied with the waiting times for telephone consulta-tions and home visits, perhaps because practice-based GPs were responding to fewer patients. Co-operative users were more satisfied with the process for making contact with the service,

contrasting with McKinley et al.’s findings8 but comparable

with Salisbury’s.5

Those attending the primary care centre reported greater

satisfaction than found previously.5This may reflect changing

public expectations and operational differences between co-operatives. Salisbury reported more (32 per cent) home visits and fewer (7.1 per cent) primary care centre and

tele-phone (57.8 per cent) consultations than we found.6[Salisbury

also included 999 or ambulance (0.2 per cent) and patients not contacted (2.4 per cent).] Attending the primary care centre appears to provide an increasingly acceptable form of face-to-face contact. However, primary care centre attenders reported less difficulty in travelling because of illness, less subsequent need for hospital care and increased rates of recovery. They may, therefore, reflect a less ill sample of people than other patients.

Primary care centre attenders tended to live slightly closer to the centre and most (95 per cent) reported arriving by car. This raises questions about equity in access to services, parti-cularly in inner city areas where car ownership and access to private transport can be limited. At the time of the study patients living at the perimeters of the district needed to travel up to 12 km to attend the centre.

Telephone consultations appear to be meeting with greater dissatisfaction than other types of consultation. Difficulty in contacting the service and expecting a home visit were asso-ciated with increased use of the A&E department, suggesting that the increase in telephone consultations may be having an impact on other providers.

These results contrast with the initial findings from the

evaluation of NHS Direct, the 24 hour nurse-led telephone advice line that is currently being piloted in England. The preliminary evaluation of the first three pilot sites suggested high general patient satisfaction with little impact to date on other service providers, although it is too soon to draw firm

conclusions.11 Whether this reflects differences between

the populations using these services and those calling out-of-hours services, a ‘novelty factor’, or differences between the organizational and skill mix arrangements between

NHS Direct and out-of-hours services is unknown.12In many

areas NHS Direct is already becoming the first point of out-of-hours contact, and it will be interesting to see whether this coincides with increasing levels of dissatisfaction emerging.

Methodological considerations

Our results may not be generalizable to smaller co-operatives, to co-operatives serving other populations, or to co-operatives with different organizational arrangements, but may reflect experiences within other inner city areas. Although we sought to control for population characteristics by undertaking the study within a single geographic area, there were significant difference in distributions between the times of calls received by the three types of organizations, which may have influenced satisfaction levels.

The response rates were lower than those obtained using

almost identical technique in Salisbury’s study.5This reflects

the difficulties of inner-city working and raises the possibility of under-representation of some patient views, particularly given a large minority ethnic population (with language differ-ences) within the district.

Conclusions

This study indicates that within an inner city area, care provided by a co-operative achieves slightly higher levels of accept-ability to patients than do deputizing arrangements. There was little evidence of greater acceptability for practice-based arrangements. Patients appear to prefer face-to-face contact (whether attendance at a primary care centre or receiving a home visit), and failure to provide this may result in increased demand being made on A&E departments.

Little is known as yet about the reasons for dissatisfaction with telephone consultations and whether this reflects unmet expectations, GP consultation skills, delays in calling patients

back, or other organizational issues.13 Strategies to improve

the quality of telephone consultations appear necessary,13

together with operational developments such as providing patient transport to primary care centres, if the quality of out-of-hours services is to be further improved. NHS Direct may have an important role to play through influencing the public’s expectations and increasing the acceptability of telephone advice.
