How GP continuity of care (GP-CoC) affects mortality in patients with type 2 diabetes (T2D) is unclear.
To examine the effect of having no continuity of care (CoC) and GP-CoC on mortality in primary health care (PHC) patients with T2D.
DESIGN & SETTING: A cohort study in patients aged ≥60 years with T2D, which was conducted within the public PHC of the city of Vantaa, Finland.
The inclusion period was between 2002 and 2011 and follow-up period between 2011 and 2018. Six groups were formed (no appointments, one appointment and Modified, Modified Continuity Index [MMCI] quartiles). Mortality was measured with standardised mortality ratio (SMR) and adjusted hazard ratio (aHR). GP-CoC was measured with MMCI. Comorbidity status was determined with Charlson Comorbidity Index (CCI).
In total, 11 020 patients were included. Mean follow-up time was 7.3 years. SMRs for the six groups (no appointments, one appointment, MMCI quartiles) were 2.46 (95% confidence interval [CI] = 2.24 to 2.71), 3.55 (95% CI = 3.05 to 4.14), 1.15 (95% CI = 1.06 to 1.25), 0.97 (95% CI = 0.89 to 1.06), 0.92 (95% CI = 0.84 to 1.01) and 1.21 (95% CI = 1.11 to 1.31), respectively. With continuous MMCI, mortality formed a U-curve. The inflection point was at a MMCI value of 0.65 with corresponding SMR of 0.86. Age and CCI aHR for death between men and women was 1.45 (95% CI = 1.35 to 1.58).
Patients with no CoC had the highest mortality. In patients having care over time, the effect of GP-CoC on mortality was minor and mortality increased with high GP-CoC.
全科医生连续性照护（GP-CoC）如何影响2型糖尿病（T2D）患者的死亡率尚不清楚。
研究无连续性照护（CoC）和GP-CoC对初级卫生保健（PHC）中T2D患者死亡率的影响。
一项针对年龄≥60岁的T2D患者的队列研究，在芬兰万塔市的公共初级卫生保健机构内开展。
纳入期为2002年至2011年，随访期为2011年至2018年。分为六组（无预约、一次预约以及改良连续性指数[MMCI]四分位数分组）。死亡率通过标准化死亡比（SMR）和调整后风险比（aHR）衡量。GP-CoC通过MMCI衡量。合并症状态通过查尔森合并症指数（CCI）确定。
共纳入11020例患者。平均随访时间为7.3年。六组（无预约、一次预约、MMCI四分位数分组）的SMR分别为2.46（95%置信区间[CI]=2.24至2.71）、3.55（95%CI=3.05至4.14）、1.15（95%CI=1.06至1.25）、0.97（95%CI=0.89至1.06）、0.92（95%CI=0.84至1.01）和1.21（95%CI=1.11至1.31）。随着MMCI连续变化，死亡率呈U型曲线。拐点处的MMCI值为0.65，对应的SMR为0.86。年龄和CCI的死亡aHR在男性和女性之间为1.45（95%CI=1.35至1.58）。
无CoC的患者死亡率最高。在长期接受照护的患者中，GP-CoC对死亡率的影响较小，且高GP-CoC时死亡率升高。
