Mortality variations as a measure of general practitioner performance: implications of the Shipman case

Making use of mortality data to improve quality and safety in general practice: a review of current approaches

OBJECTIVE

To review studies of the use of mortality data in quality and safety improvement in general practice.

DESIGN

Narrative review.

METHODS

Search of Medline, Embase and CINAHL for articles reporting mortality monitoring or mortality reviews in general practice. The included articles were reported in English and of any study design, excluding case reports and comment pieces. Studies of palliative care and bereavement, and of primary care programmes in developing countries, were excluded.

RESULTS

229 articles were identified in the searches, 65 were identified as potentially relevant and 53 were included in the review. The studies addressed the impact of primary care provision on mortality rates, methods of monitoring mortality, and the role of audit and death registers in quality and safety improvement. General practitioners were interested in using mortality data but reported difficulties in obtaining complete information. There were no experimental studies of the impact of the use of mortality data, and little evidence of long-term systematic initiatives to use mortality data in quality and safety improvement in general practice.

CONCLUSIONS

Mortality data are not used systematically in general practice although general practitioners appear interested in the potential of this information in improving quality and safety. Improved systems to provide complete data are needed and experimental studies required to determine the effectiveness of use of the data to improve general practice care.

A practical method for monitoring general practice mortality in the UK: findings from a pilot study in a health board of Northern Ireland

BACKGROUND

The Baker report into Dr Harold Shipman's murders recommended monitoring mortality in general practice, but there is currently no practical method available to implement this.

AIM

To monitor mortality rates in response to the Baker report and to use the data to improve quality of care.

DESIGN OF STUDY

Prospective mortality monitoring study.

SETTING

Eastern Health and Social Services Board, Northern Ireland.

METHOD

Linked quarterly mortality data from 1994-2001 were compiled for 114 general practices in Eastern Health and Social Services Board in Northern Ireland. Cross-sectional control charts compared crude and adjusted mortality rates across all the practices. Longitudinal control charts analysed quarterly mortality rates over 28 quarters within each practice. Practices were sent their own control charts and invited to feedback workshops. Special cause variation in mortality was investigated as follows: checks on data, case-mix, practice structures, processes of care and finally individual carers.

RESULTS

Age, sex and deprivation adjusted cross-sectional control charts identified 18 practices as showing special cause variation in their mortality (11 high and 7 low). Assignable causes were found for all high special cause practices: large numbers of nursing home patients (six practices), very high levels of deprivation and high morbidity not captured by our case-mix adjustment (five practices). For three of seven low special cause practices, case-mix adjustment underestimated affluence and overestimated morbidity levels. Feedback indicated widespread support for the principle of monitoring, but concerns about the public disclosure of mortality data.

CONCLUSIONS

We have successfully developed and piloted a general practice mortality monitoring system with the support and participation of local stakeholders. This used control charts for analysis and followed a scientific strategy for investigating special cause variation.

Impact of nursing home deaths on life expectancy calculations in small areas

STUDY OBJECTIVE

The drive to tackle health inequalities at the local level has increased interest in mortality data for small populations. There is some concern that nursing homes may affect measures of mortality for small populations, but there has been little in depth analysis of this.

DESIGN AND SETTING

Deaths between 1997 and 2001 and population figures from the GP register (Exeter) database and census 2001 were used to produce life expectancy (LE) figures for all electoral wards in West Sussex. The proportion of those dying within each ward that had been residents of nursing homes was calculated and the relation between these variables and deprivation investigated.

RESULTS

There was a significant linear relation between nursing home deaths and LE (p<0.0001), which explained 36% of variation in LE between wards. Deprivation accounted for around 35% of the variation in LE (p<0.0001) but was not correlated with nursing home deaths (p> or =0.0982). Multiple linear regression shows that over 60% of the variation in LE at ward level can be explained by both nursing home deaths and deprivation (p<0.0001) and that the two variables explain similar proportions of this variation. The relation between LE and nursing home deaths within wards grouped by deprivation suggests that the impact of nursing homes is strongest in deprived wards.

CONCLUSIONS

This finding has important implications for LE calculations in small populations. Further investigation is now needed to examine the impact of nursing homes in other areas, on other mortality measures, and in larger populations.

Monitoring mortality in general practice in Grampian, Scotland

Information on the distribution of mortality and morbidity in general practice is scarce, and not easily accessible either by health authorities or individual general practices. Although the assessment of population mortality is a standard public health measure, colleagues in public health, information sciences and general practice rarely undertake such activity related to general practice populations. Mortality information can be used for various purposes. Examples are providing background data for clinical audits or alerting practitioners to quality issues in the healthcare industry or even suggesting environmental hazards. We measured the experience of mortality in all generally practices in Grampian in the years 1991 to 1999. All practices were notified of their actual and expected mortality over this period of time and asked for comment. Only three general practices had excess mortality experience in both the periods 1991 to 1995 and 1996 to 1999. Only a minority of practices commented on the results. It appears that a high presence of nursing homes in a practice might skew the results; this phenomenon will be central to further inquiry. Future methodology for recording death in general practice should take account of this, as well as providing an account of the qualitative aspects of patients' need for a dignified satisfactory death.

A realistic approach to the evaluation of the quality management movement in health care systems: a comparison between European and African contexts based on Mintzberg's organizational models

The quality movement is gaining momentum worldwide in the field of health care. Initiated in industrialized countries, it steadily grows in Africa. However, there is no evidence that approaches designed to address issues in a given organizational context have the same effect in another one where issues present differently. Along the epistemological paradigm of realistic evaluation proposed by Pawson and Tilley, we use Mintzberg's organizational models to compare the configurations of European and African health care organizations and the trends followed by the quality management movement in both contexts. We illustrate how European health systems traditionally emphasize professional autonomy while African health systems are structured as command and control hierarchical systems. We illustrate how the quality movement in Europe emphasizes standardization of procedures, a characteristic of a mechanistic organization, while excessive standardization is part of the quality problem in Africa. We suggest that instilling professionalism may be a way forward for the quality movement in Africa to improve patient focus and responsiveness of responsible professionals. We also suggest that our interpretation of broad trends and contrasts may be used as a useful departure point to study the wide contextual diversity of the African experience with quality management.

Is it possible and worth keeping track of deaths within general practice? Results of a 15 year observational study

AIM

To assess the value of maintaining a death register in a general practice with particular reference to monitoring quality of care.

DESIGN OF STUDY

Observational study.

SETTING

Inner London general practice.

METHOD

The practice maintained a manual death register, retained medical records of all deceased patients, and requested information on cause of death from health authorities and coroners for 15 years.

MAIN OUTCOME MEASURES

Number and causes of deaths; 3 yearly age standardised death rates; proportion of deaths formally notified to the practice; place of death; source of cause of death information.

RESULTS

During the study period 578 patients died. Practice age standardised death rates fell significantly from 35.59 to 27.12/1000. 498 (86.2%) deaths were formally notified to the practice, 392 within 7 days of death. Of 143 deaths reported to the coroner, only 45 coroners' reports were received. 360 (64.1%) died in hospital, 139 (24.8%) at home, and 38 (6.8%) in a hospice. Death certificate cause of death information was obtained from patients' records in 33.6% (n=194) of cases and from health authority sources for 50% (n=289). The pattern of ascertained causes of deaths was similar to the national pattern.

CONCLUSION

A death register can examine trends in practice deaths by age and place of death and comparisons undertaken with nationally published mortality data. An accurate picture of cause of death cannot be generated from routine data flows alone. There is delay in informing GPs of patient deaths. Meaningful and timely monitoring of deaths cannot be undertaken by individual practices. National Statistics should provide routine analysis of GP death certificate information.

An analysis of practice-level mortality data to inform a health needs assessment

BACKGROUND

The utility of practice death registers has been indicated but, in the wake of the recent Harold Shipman case in the United Kingdom, the value of individual practice-level analysis has been questioned.

AIM

To assess the value of analysing practice-level mortality data to inform health needs assessment.

DESIGN OF STUDY

Comparative analyses of mortality.

SETTING

Two large practices, an inner-city study practice, and a reference practice in a medium-sized town.

METHOD

All premature deaths (aged one to 74 years) during 1994-1998 at the study practice (n = 170), and reference practice (n = 340), were identified. Cause-specific standardised mortality ratios (SMRs) were calculated using national reference data. The proportions of the total number of years of life lost (YLL) up to age 75 years associated with alcoholism, drug dependency, and severe mental illness were calculated and a comparison between practices was made, using standardised proportional mortality methods.

RESULTS

Significantly raised SMRs for the study practice were lung cancer (SMR = 234), digestive system diseases (SMR = 362), and injuries and poisonings (SMR = 180). Having standardised for age, there were nearly four times as many YLLs in the study practice population associated with a history of alcoholism, and over three times as many associated with drug dependency, compared with the reference practice.

CONCLUSION

Mortality analyses can provide useful insights for informing needs assessment in an individual practice. Small number problems may occur with smaller practice populations, but collation of data at PCG/T level also has potential utility. The study reinforces the argument that practices need to set up and maintain complete and accurate death registers.

Practice nurses and their 'lived experience' of clinical supervision

Increased workload in primary care and the advent of primary care groups means that practice nurses (PNs) are experiencing a profusion of changes. As a result, PNs have taken on board many new skills, and this has increased the demands and stresses made upon them. Accordingly, this study investigated 17 PNs' lived experiences of clinical supervision following a 4-day training programme. It adopted a hermeneutic, phenomenological method. Data were collected by means of semistructured interviews within a series of focus groups. The data from the focus groups underwent a thematic analysis, which induced an emerging theory comprising five key themes: (1) providing support (2) nurturing and growth (3) enhancing and enriching practice (4) encountering a new experience, and (5) engaging in intellectually challenging and demanding work. The findings indicated that the central theme of the PNs' experience of clinical supervision was that of 'providing support', in that, without the presence and application of support, the effectiveness of the other themes appears to be diminished. The findings additionally indicated a range of issues, discussed under the headings: practice, education, policy, and further research.
